We're dividing 21589128 by 758 
Our goal is to divide 21589128 by 758.

Moving on to step 1:
758 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 758

Advancing to step 2:
The number 758 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 758

On to step 3:
758 goes into 215 0 times with a remainder of 215.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 215 leaves us with 215.
Take the next digit (8) from the dividend and append it to 215, then repeat: 2158 / 758

Step 4:
758 can be fit into 2158 2 times, resulting in a remainder of 642.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1516 from 2158 to get 642.
Bring next digit (9) of the dividend behind the 642 and repeat the process: 6429 / 758

Step 5:
The number 758 fits into 6429 8 times, leaving a remainder of 365.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 6064 from 6429 and we're left with 365.
Append the next digit (1) from the dividend to 365 and continue with: 3651 / 758

Step 6:
When dividing 3651 by 758, we get 4 with a remainder of 619.
The next digit of our result is 4. 
Result so far: 284.0
If we take 3032 away from 3651, we end up with 619.
Include the next digit (2) from the dividend after 619, then repeat: 6192 / 758

Step 7:
758 goes into 6192 8 times with a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 2848.0
The remainder is 128 after subtracting 6064 from 6192.
Grab the next digit (8) from the dividend, add it to 128, then carry on: 1288 / 758

Going ahead to step 8:
When dividing 1288 by 758, we get 1 with a remainder of 530.
Write down 1 as next digit of the result. 
Result so far: 28481.0
If we subtract 758 from 1288, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 9:
758 can be fit into 5300 6 times, resulting in a remainder of 752.
Use 6 as the next digit of our solution. 
Result so far: 28481.6
Deduct 4548 from 5300 and we're left with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Advancing to step 10:
The number 758 fits into 7520 9 times, leaving a remainder of 698.
Put 9 as the next digit of the answer. 
Result so far: 28481.69
Subtracting 6822 from 7520 leaves us with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Step 11:
When dividing 6980 by 758, we get 9 with a remainder of 158.
Put 9 as the next digit of the answer. 
Result so far: 28481.699
Deduct 6822 from 6980 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Our division results in 28481.699 with a remaining 0.0158.
